Programmatically get webform submitted field values

Question

How can i print/echo the submitted value of specific field in from a webform? I need to do this in the webform 2 PDF module so i can better customize the output of generated PDFs. Im fairly new to Drupal so an example of how to get a simple f_name filed would be great.

I'd also like to start getting more involved with the Webform API too.

i.e

First Name: SUBMITTED NAME VALUE

Answer 1

To get webform values right after the page submit, they're stored in the global $_POST variable.

Alternatively you need to load the right webform submission.

Drupal 7

Here is example how to do it in Drupal 7 (as per this post):

module_load_include('inc', 'webform', 'includes/webform.submissions');
$submissions = webform_get_submissions(array('nid'=> 123));

foreach ($submissions as $submission){
    foreach ($submission->data as $row=>$data){
        print '<pre>'; print_r($row); print '</pre>';
        print '<pre>'; print_r($data); print '</pre>';
    }
}

Drupal 8

Here is the example to get the webform submission in Drupal 8:

$entity = \Drupal::entityTypeManager()->getStorage('webform')->load('my_webform');
$form = $entity->getSubmissionForm();
$elements = $form['elements'];

Here is the example using drush:

drush ev 'print_r(\Drupal::entityTypeManager()->getStorage("webform")->load("repairs_taps")->getSubmissionForm()["elements"]);'

Answer 2

In recent 3.x and 4.x versions of webform it has an hook based API to allow you do stuff with submitted webform values.

Look at like hook_webform_submission_insert() or hook_webform_submission_update() (if your webform has Drafts enabled for instance the final submission is an UPDATE call with isNew == False and isDraft == False).

The functions take a parameter $submission that is a PHP array of the submitted form values ... You can do whatever you want with them from there.

Answer 3

In Drupal 5-7 it looks like one can use the webform_get_submissions function.

Answer 4

Drupal 8 solution:

$entity = \Drupal::entityTypeManager()->getStorage('webform')->load('my_webform');
$form = $entity->getSubmissionForm();
$elements = $form['elements'];

At the moment there is no function webform_get_submissions() in Drupal 8 (as exists in D7 and D6). Above lines can help to get the submissions of a specific webform.
